Problem 2 (10 pts)in standard dns, the transaction identifier (txid) is a 16-bit random identifier that links a dns query to adns response. in class, we already discussed how a phenomenon similar to the birthday paradox makes itrelatively easy for the attacker to guess the txid of at least one of several dns queries sent by a recursivedns server to a name server as a result of the same number of fake queries submitted by the attacker to therecursive dns server. if the txid size were increased to 32 perfectly random bits, using the same reasoningused in class, calculate how many fake queries and fake responses would the attacker have to submit to therecursive dns server, in order to have a probability of dns cache poisoning success of at least 50%.
